3dScanned Data

[CycloneWade]

Does anybody have any experience with using 3d Scanned Surfaces to make parts that would eventually have the same curvature and shape as the scanned surfaces?

Thanks.

Is this a SW question or some type of 3D data for a 3d printer question?

I already have the surface data from the scanner just looking for some tips on how to use it. I have a few techniques but was looking for some others inputs. My method involves moving and rotating the surface back to the origin and using composite curves to get the shape from a converted sketch. And using that sketch to cut through a solidbody of sorts. So, I guess there is no real question here, just maybe some tips.

We have had white light scans done to old tooling on vane sections for cast aluminum torque converters were the originals were made off of mocked up plastics that were no longer availible. The best thing to do from my experiances is to construct composite curves, 3d sketches and create surfaces and cut and trim them together to make a solid or do as you are doing and use the surfaces to cut to on a solid. You might want to also look at adding the surfaces to an assembly and creat a nother surface part off of your scan data by constructing it in the assembly as an edit part. Or you could also use multie bodies in one part, what ever you are more comfortable with.

Look up GeoMagic Raindrop software. That's what it does. They may be able to point you to a company that does this as a service, as well.

The crux of this problem probably has to do with the format of the scanned surface data. I presume it is in point cloud format. As far as I know, there are two basic choices from this point:
1) Import the points and create your own surface that goes through (or approximately goes through) them
2) Use other software to turn the points into a surface that Solidworks can handle
It sounds like you're already using technique #1. I also had fairly good results using curves through free points and surface lofts, but it was tedious. I've never used Rhino, but it looks like it could be useful for this and seems to be fairly reasonably priced. McNeel has a tutorial on using it with Solidworks at:
